You must be excited! Most of it works quite well. I have a few thoughts: Are you planning on your son and daughter sharing a bathroom? Is bedroom #4 a guest bedroom? If you have 3 bathroom, why not give each of your children their own? especially since they are different sexes and getting older. I would make bath #2 an en suite bath for bedroom #3. Swap the laundry room and bathroom #3. Then bedroom #2 can use bath #3. You can keep direct access to bath #3 from bedroom #4 if you'd like. The dining space in the family room looks tight. Make sure it fits your table. Make sure there's enought elbow room for the toilet in the master bath. The door from the garage should swing into the home.

Bathrooms: as others have pointed out, you should have a full bath on any floor where there might be sleeping rooms. If you intend to ever sell this house, there should be a full bath on the 2nd floor and in the walkout basement. (Currently, it looks as if the master bath is the only full bath in the plan.) The laundry location will be very annoying to anyone who has more than a single couple in the house--they go up/down stairs, **across the house**, up stairs and then into a laundry room. Stairs: How do you go downstairs? Do you really want the stairs between the great room and the kitchen? The stairs take up a lot of room in the middle of the house--especially considering you don't intend to use them often. Accessibility: By adding stairs to the master bedroom, the master bedroom will not be accessible to someone with limited mobility. As others have pointed out, that negates some of the advantages of a first floor master. Kitchen/Hearth area--there's a lot of space there but I'd be concerned about the actual cabinet layout before I started building. Since the back wall is primarily windows, that will influence how the cabinets are laid out. You'll also want to be sure there's sufficient room for a large table, since that is your only eating space--at least, I assume there will be eating space in there someewhere! Although the space is large, it is fulfilling 3 functions: kitchen, dining, "hearth". Entry way: The entryway looks as if it's over 160 square feet. At even *cheap* construction costs, do you really want to spend $16,000 for an entryway? It is large and will be a huge empty space when you enter the house. What is the purpose of having it so large? I guess you could put a large sculpture in the middle. Flows: The pathways from the garage to the kitchen or garage to the bedroom or garage to the great room are all filled with turns. I think the flow could be improved. Pantry/Officette: What exactly is an officette? How would furniture be arranged here? Pantry shelves don't need to be very deep--the room is too wide to just be a pantry, but isn't really big enough to be an office. Also, does it make sense for one of you to have an 'officette' in an INTERIOR room when the laundry room and mud room both get windows? Office: At that size, it should be big enough to share. If you don't want to share it, I'd consider making two separate offices. For that matter, I'd consider making them "bedrooms" with the intent of using them as offices. That would mean putting in a closet--and turning the powder room into a full bath (or adding another bath). Master bath: There is a lot of wasted space here--it looks as if it's about 11' from the vanities to the shower--that's an entire room--all empty space. The tub gets a back window, but there's a lot of unused space in front of it--on top of all the empty space in the middle of the master bath. Master closet: Some people don't like walking through a bathroom to get to a closet, but that doesn't bother me. What does bother me is what you're gong to do with an 11' wide closet. I *like* big closets, don't get me wrong. But closets are most valuable along the walls--what are you going to do with that space in the middle? Some people put dressers and benches in the middle, but if you're going to do that, what are you going to put in the 16x18 bedroom? Foyer to master bedroom: It is big enough to walk through, but not really big enough to put furniture in. You said your girlfriend was interested in making it a sitting room, but given that you have a HUGE bedroom, a great room, and a hearth room, why would you consider putting a sitting area in an interior, private space near the laundry? Owners Suite to bathroom: I can't tell if there's really supposed to be a door there--it looks too big for a pocket door--and most people do want a door to their master bath, since couples don't necessary get up at the same time. I admit that a 4.5 car garage would be fun to have :-). I'm afraid I don't like this plan--it doesn't use space well, I don't think it'd be easy to live in--even looking at it as a two person house, and you'd be walking through a lot of open space. This house is big and would take a lot of money to build--and I don't think it's a particularly livable plan. I think you ought to look at a lot more existing floor plans or find yourself an architect.

One of the problems you'll have to figure out is how to hold up the houses on the hill. Generally, this is done with a foundation / retaining wall. Without knowing the soil type, it would be difficult to figure out how the retaining wall would have to be constructed. Generally, you can think of a retaining wall as being an "L" shape with the horizontal leg of the "L" being on the uphill side so that the weight of the soil holds the vertical portion upright against the soil pushing against the vertical wall section. There can be a 1:1 (or greater) relationship between the vertical and horizontal legs depending upon the soil type, This means that a 12-foot high vertical wall would need at least a 12-foot horizontal section to retain the wall. You have to excavate the hill back, pour the horizontal and vertical wall sections - and then backfill the soil against the vertical wall. You'd really need a structural engineer to do this type of design, as if it is not calculated correctly and then built to match the structural plans, you'll have the entire building sliding down the hill. An alternative might be caisson (drilled) foundations - but that requires a caisson drill and access to the site where the foundations would be placed. You could also cantilever the houses off of the hill side - but, that's some real involved structural work. One other thought - while you're planning on a composting toilet - have you thought about how to dispose of the grey water (shower, sinks)?

Wow. Thank you all for the comments. I feel like I have blinders on and my eyes are suddenly open. How can I not see all these things? I just can't. But, once you point it out to me.....it all looks so obvious. Keep reading here and soon you'll see these things too. Don't rush towards building. I have to say it -- I buck the tide here on front-loading garages and think they generally look fine, and there are always good reasons to have them, even if there's apparently enough property to support not having them. Yeah, I'm fine with front-facing garages, but they aren't all done right. Garages can't just be stuck on -- they take planning just like any other part of the house.
